Layer toggles, filtering, and grouping logic
Data handling & performance:
Convert & serve large datasets (1–20GB+) efficiently as vector tiles (MBTiles/Cloud storage)
Optimise rendering for smooth performance at scale
Web platform features:
Build as a secure website (desktop + mobile responsive)
User login system (accounts & authentication)
Payment integration (Stripe or similar) for paid access tiers
Role-based access (free vs paid features)
Back-end & hosting:

APIs for user authentication and serving vector tiles
Modular, well-documented codebase for long-term maintainability
Deliverables:

Prior work with secure login systems and subscription/paywall models
Please share:
1. Examples of mapping applications you’ve built
2. Your experience with MBTiles/vector tiles and payment integration
